The objective of this project is to develop ultralight radiosondes for long-term measurements in the stratosphere.
This project won First Award and the Craig R. Barrett Award for Innovation at ISEF, the world's largest student sience competition. In addition, the project won national first prize at Jugend forscht, Germany's largest youth science competition.

On the previous stratospheric flights, the sondes were able to stay in the air for 25 days and circumnavigate the world several times.
The 4th generation radiosonde adds support for aerial imaging.
